Globally, the number of single people is on the rise. Rates of marriage and cohabitation are on the decline, and in some countries, even sex itself is down. In this new series we're on a journey around the world to find out why people seem to be coupling up less, and what could be causing this dating crisis. In this episode, we’re in the UK

Olly Robbins’s testimony will have been painful for the PM. The No 10 omnishambles was publicly laid bare – and Keir’s fresh out of scapegoats

‘How dare Olly Robbins not have made me look like a chaotic, unprincipled plonker?” is an interesting defence for a prime minister to go for. But we are where we are. Never mind “this is the future liberals want”: this is the past that Keir Starmer wants. What follows is the alternative branch of history the endlessly victimised PM apparently wishes we’d lived through instead.

In this version, he chooses a career liability to be US ambassador, who is well known to have been big pals with a notorious sex trafficker of underage girls and to have spent years involved in questionable business associations, some with Russian and Chinese firms. He immediately announces the appointment. When that guy is deemed a risk by the famously stringent developed national security vetting process – seriously, who’d-a-thunk-it?! – then Starmer has to go out and tell the public that the wrong ’un isn’t actually going to be his US ambassador after all, for “reasons”. Not to be one of the many people who has to explain how basic politics works to the PM, but after that notional fiasco, we’d have spent a very long time indeed talking about his bad judgment. Just like we are now. It’s almost as if all branches of history lead to a discussion about Keir Starmer’s bad judgment. The only person who doesn’t judge this to be the situation is Keir Starmer, which is another instance of his bad judgment. Monday found him chuntering away at the dispatch box like an arsonist complaining about the price of matches.

Richard Gadd’s at it again. His unforgiving new drama tackles the damage men do to each other head on, by pulling out his insides and smearing them everywhere. Every man should watch this queasy masterpiece

We have known for some time, I think, that men are not OK. Richard Gadd’s new drama, conceived before his astounding, semi-autobiographical creation Baby Reindeer sent his reputation stratospheric, and now broadcast in the slipstream of that success, is a fiercely intelligent, unforgiving, harrowing attempt to show us how and why.

Half Man begins in the present, with two men circling each other in a dark barn. One, Niall (Jamie Bell), is in full Scottish wedding fig. The other, Ruben (Gadd), is stripped to the waist and has his hands wrapped like a sparring boxer. The fight that is surely about to come does not seem a fair one.

Knowing the difference between hunger and appetite, and understanding the sensory cues behind them, can help us make better decisions about what we eat

Imagine you’re in a meeting room when someone brings out the biscuits – a packet of Jammie Dodgers, perhaps, or a nice little plate of custard creams. Maybe you want one and maybe you don’t, but the chances are the people around you are all responding differently: someone will grab a couple straight away, someone else will eat one without seeming to notice, another will barely be aware the biscuits exist, and someone will spend the whole meeting wanting one but not taking it. Our appetites and responses to food vary wildly – but what’s going on behind the scenes to govern them? And has modern food somehow hijacked the process? Grab a biscuit (or don’t) and settle in.

“First, it’s important to distinguish between hunger and appetite,” says Giles Yeo, a professor of molecular neuroendocrinology at the University of Cambridge and the author of Why Calories Don’t Count. “Hunger is a feeling – it’s what happens in the run-up to you deciding you need to eat something. Appetite is everything that surrounds why we eat – including hunger, fullness and reward, or how you actually feel when you eat. Those three sensations all use completely different parts of the brain, but they all work together.”

Mousehole in Cornwall once had a butcher, post office and general store. Now it doesn’t even have an ATM – and one of its crucial bus services has been cut. Can residents save this vital resource?

It’s early April and the sun is shining over Mousehole, Cornwall, as an older couple trudge up the hill to their nearest bus stop before sinking into two of the plastic chairs that have been lined up on the side of the road. Until recently, buses would come right to the centre of the fishing village, the couple are soon explaining to a pair of Australian tourists also waiting for the bus. But when the bus route was taken over by the Go-Ahead transport group in February, the small, ice-cream-van-like buses that had been used by the previous bus company, First Bus, were swapped for full-size buses – some of them double deckers – that wouldn’t be safe to drive through Mousehole’s narrow streets. So the route, which has been taking passengers down to the harbour since the 1920s, was cut short, and now ends at the edge of the village.

You don’t have to spend long in Mousehole, described as “the loveliest village in England” by the Welsh poet Dylan Thomas, to learn of residents’ dismay over this change. “Save Our Stop” flyers have been stuck in the windows of houses and businesses, while a banner adorns the railing next to where the old stop used to be, inviting passersby to sign the petition to have it reinstated and “make Mousehole accessible to all again” – a petition that now has more than 5,000 signatures.

Our Legacies of Enslavement team has found humanity and dignity, not blame or guilt, are at the heart of the conversation

Guardian owner heralds next phase in Legacies of Enslavement restorative justice plan

There’s an image, a feeling, that I haven’t been able to get out of mind since my last visit to the Sea Islands, US, in March. That of living in a small box, compressed on all sides. From above, your basic services are being neglected or withheld; from the sides, your ability to find a job or make a living is cut away; from below, a steady assault on your self-esteem as you are criminalised, ignored, gaslit or made to feel invisible. And imagine having to raise a family, make ends meet, maintain your physical and mental health in that box. At some point the air is going to thin out.

Occasionally, a glimpse of something offers respite. A flock of birds against the sky. The sway of the Spanish moss on the oak tree that has binya (“been here”; a Gullah Geechee term used to describe Sea Islands natives) for hundreds of years, that has seen Jim Crow, Reconstruction and maybe even enslavement. You hear the flow of the water as it laps against the dock. The water that represents a passage to the motherland. And life feels worth living.

Sacked civil servant discloses he overturned vetting ruling without knowing full extent of national security concerns

• UK politics live – latest updates

The sacked senior civil servant Oliver Robbins has said he was subject to “constant pressure” when he started working at the Foreign Office to get Peter Mandelson in post as soon as possible.

He said the Cabinet Office urged the Foreign Office to allow Mandelson’s appointment as the UK’s ambassador to the US without the usual vetting process but the Foreign Office pushed back and the vetting eventually went ahead.

Olly Robbins told MPs he had been asked to get the ex-No 10 aide a role and not mention it to then Foreign Secretary David Lammy

The hearing has started.

Emily Thornberry, the chair, started by saying that Robbins did not tell the whole truth about this process when he gave evidence to it in November.

Sacked civil servant says it was right not to tell PM that Mandelson had failed vetting – a view Starmer rejects

In the last 24 hours, the two men at the heart of the Peter Mandelson vetting scandal have given their version of events: Keir Starmer, the prime minister, and Olly Robbins, the man he sacked as the head civil servant at the Foreign Office.

Robbins’ testimony to the foreign affairs select committee on Tuesday completes much of the picture as to why Mandelson was given security clearance against the advice of vetting officials.

Donald Trump said on Tuesday that he expects to resume bombing Iran, as a fragile 14-day ceasefire approaches its deadline Wednesday with no deal in sight.

“I expect to be bombing because I think that’s a better attitude to go in with,” Trump told CNBC’s Squawk Box. “We’re ready to go. The military is raring to go.”
